Abstract :ABSTRACT In this study the effect of a new synthetic Schiff base namely bis -insert ignore into journalissuearticles values(2-hydroxy-3-methoxy);-1,6-diaminohexane salicylaldimine on the corrosion and dezincification of a 70/30 brass in 1M HCl has been studied using weight loss , electrochemical insert ignore into journalissuearticles values(polarization & impedance); and solution analysis techniques. Results obtained revealed that this compound is very good inhibitor and behaves as mixed type of inhibitor for brass 70/30 in this acid medium. Solution analysis and surface composition insert ignore into journalissuearticles values(weight%); of the alloy in the presence and absence of inhibitor by atomic absorption spectroscopy insert ignore into journalissuearticles values(AAS); and energy dispersive X-Ray analysis insert ignore into journalissuearticles values(EDAX); revealed the decrease in dissolution of both Cu and Zn in the presence of this inhibitor. The dezincification factor insert ignore into journalissuearticles values(Z); was calculated by using analysis solution.     Key Words : Inhibitor, polarization, impedance, dezincification, corrosion.
Keywords : Inhibitor, polarization, impedance, dezincification, corrosion
